DEEP-WELL PUMP.

'To all /wwm t may concern: i

Be it known that I, VILL L. JONES, citizen of the United States, residing at Douglas, inthe county of Cochise and State of Arizona, have invented new and useful Improvements in Deep-Well Pumps, of which the following is a specification.

lIhis invention relates to pumping mechanism for deep wells.

One object of the invention is to produce a simple and improved construction and arrangement of parts including a working barrel and plungers'reciprocating therein in opposite directions to producel a steady or constant flow, the construction being such that a foot valve may be dispensed with.

A further lobject of the invention is to simplify and improve the construction of the plungers, each having a single valve and valve seat, thereby avoiding leakage which is liable to occur when a valve is provided which must simultaneously engage two seats.

A further object of the invention is to simplify and improve the general construction, arrangement and combination of parts constituting the invention.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same cone sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired. l

In the drawing, Figure 1 is a vertical sectional view illustrating a portion of a well casing, a working barrel, the plungers operating therein, the solid and the tubular plunger stems, and the packing boxes through which said stems are guided. Fig. 2 is a vertical sectional view taken through one of the plungers, said view being on a larger scale. Fig. 3 is a transverse sectional view taken on the line 3 3 in Fig. 2. Fig. 4 is a transverse sectional view taken on the line 4 4 in Fig. 2.

` Application led April 26, 1915.

serial No. 23,902.

Corresponding parts in the several figures are denoted by like characters of reference. The well casing 15 is provided at its upper end with a laterally extending discharge spout 16 and with a packing box 17 through which a tubular plunger stem 18 is guided,

said tubular plunger stem terminating at.

casing, has an inlet 22, and within said barrel the upper and lower plungers 23 and 24 are arranged, said lower plunger being connected with and carried by the interior plunger stem 20, while the exterior tubular plunger stem 18 carries the upper plunger 23. The plungers, which are mounted on the respective steams for limited sliding movement, are of identical construction, each.

comprising an annular cylindrical body 25 having a valve seat 26 at its lower end and provided with inwardly extending radially disposed wings or ribs 27 having upwardly extending bolts 28. -The valve rings 29 and packing leathers or cups 30 are disposed in alternate order on the annular base and eX- tend upwardly therefrom, the uppermost valve ring being provided with inwardly extending lugs 31 through which the bolts 28 extend, said bolts extending also through lugs 32 formed on the sleeve 33 which slidably engages the plunger stem, it being obvious that said sleeve is suitably proportioned to engage the inner or outer plunger stem, as the case may be. The parts are assembled together by the nuts 34 which are threaded upon the bolts 28 and tightened against the flange 32 of the sleeve 33.

The inner and outer plunger stems are equipped with valves 35, 36 adapted to e'ngage the seats 26 of the plungers 23 and 24, respectively. The slidable movement of said plungers on their respective stems is limited by stop members which may be in the nature of flanges or collars 37, 38 fixed on the stems 20 and 18, respectively.

In operation, the stems 18, 20 may be reciprocated in opposite directions vby means of a pumping jack of suitable construction which, however, has not been illustrated, as it forms no part of the present invention. When the inner stem 20 is moved downwardly, and the tubular stem 18 is moved upwardly, the valve of the lower plunger will be unseated, permitting fluid to move upwardly through the plunger body. The valve of the upper plunger will be seated,

. causing Huid to be lifted by said upper plunger.

Vhen the movement is reversed, the valve of the upper plunger will be unseated, permitting upward flow through said upper plunger of liquid which is now forced upwardly or lifted by the action of the lower plunger, the valve of which is now seated. Each valve having but a single seat, there is no opportunity for unequal wear upon the valve seats which in many devices at present in use results in leakage involving the loss of a great deal of time in making the necessary repairs. The packing boxesfor the respective plunger stems are located at the surface, and any leakage at these points may be quickly and efectually checked by by the' bolts, nuts on said bolts whereby the parts are assembled, a valve carried by the stem and engaging the seat formed on the base, and va stop member fixed on the stem to limit the slidable movement of the plunger.

In testimony whereof I affix my signature in presence of two witnesses.
